Octarius War

The Octarius war is the most hilarious and fail venture the Imperium has ever made. And believe us, that is no small feat.

The Imperial Guard were having their asses handed to them by the Orks on the planet Ghorala in the Octarius system. Former Lord Inquisitor Kryptman, leading expert on the Tyranids decided that the best solution would be to sic a recently captured swarm of Tyranids on the Orks and letting the two fight it out, the IG would then mop up the remaining survivors. The obvious flaw in his plan of course is that both Nids and Orks thrive on war, being unintentional experts at biological warfare, meaning the survivor will emerge much stronger than ever before. The conflict has currently devolved into a massive meat grinder and the Orks are fucking loving it.

This tale is notable for being one of the few bits of fluff in the Nid 'dex where they don't get their arses handed to them by space communists, poncey faggots or fucking smurfs

Never mind on the Eldar part, they're currently trying to clean up Kryptman's mess by bio-purging the front line and worlds around it.
